AMSOIL 100% Synthetic CVT Fluid
AMSOIL 100% Synthetic CVT Fluid is a purpose-built synthetic transmission fluid for passenger car and light-truck continuously variable transmissions that run a steel belt or chain between variable-diameter pulleys. The formulation targets the metal-to-metal friction profile CVTs demand, with wet-clutch anti-shudder performance, thermal stability, and cold-flow protection for daily-driver and severe-service use across a broad list of factory specifications.
Metal-to-metal friction tuned for belt and chain CVTs
CVTs transmit torque through a thin steel belt or chain pressed between two variable pulleys. The fluid must hold the belt against the pulley without slipping while still allowing smooth ratio changes. AMSOIL 100% Synthetic CVT Fluid is engineered to deliver exceptional metal-to-metal frictional properties that help prevent belt and chain slippage and extend transmission life, supporting consistent shift quality as the transmission learns and adapts.
Anti-shudder durability for wet-clutch operation
CVTs rely on wet clutches and torque converters with friction surfaces that can chatter if the fluid loses its frictional balance. Based on JASO LVFA Anti-Shudder Durability testing, AMSOIL Synthetic CVT Fluid lasted six times longer than the test baseline, translating to improved anti-shudder durability and reduced noise, vibration, and harshness over the service interval.
Wear protection under torque load
CVT bearings, pulleys, and the belt or chain itself see high contact pressures during launch, hill-pull, and trailer use. In FZG gear-scuffing testing under ASTM D5182, AMSOIL Synthetic CVT Fluid surpassed a 12-stage pass, indicating strong load-carrying capacity and resistance to scuffing under severe service.
Thermal stability and varnish resistance
Heat is the primary enemy of any CVT fluid. With a flash point of 218°C (414°F) under ASTM D92 and a fire point of 238°C (435°F), the synthetic base oils and additive package resist thermal breakdown. The formula also guards against varnish that can foul valve bodies and pressure regulators, helping the transmission hold proper line pressure as the fluid ages.
Cold-weather flow without dilution tricks
Cold-start performance matters in any region with real winters. AMSOIL Synthetic CVT Fluid carries a Brookfield viscosity of 9,051 cP at -40°C under ASTM D2983 and a pour point of -46°C (-49°F) under ASTM D97, supporting prompt lubrication of the chain or belt, pulleys, and valve body during cold-temperature starts.
Field-proven in severe service
AMSOIL 100% Synthetic CVT Fluid was installed in four Las Vegas taxis, each driven 100,000 miles in stop-and-go heat, climbing, and high-mileage commercial duty. The taxi belts pulled from those transmissions showed the formula delivers outstanding protection in severe-service conditions outside a laboratory.
Recommended applications and service intervals
AMSOIL 100% Synthetic CVT Fluid is recommended for belt-type and chain-type continuously variable transmissions in passenger cars and light trucks that call for one of the factory specifications listed for product CVT. The match should be confirmed against the owner manual or the AMSOIL vehicle lookup guide before ordering.

- Service interval follows the vehicle manufacturer recommendation in the owner manual, with a shorter interval for tow, taxi, mountain, dusty, or extreme-temperature use.
- Not intended for dual-clutch transmissions, conventional planetary automatics that call for ATF, manual gearboxes, or off-road ATV and UTV CVTs that specify a powersports-specific belt-drive lubricant.
Pair fluid changes with the OEM transmission filter or strainer service when the vehicle manufacturer calls for it, and follow factory fill-and-level procedure, including any required adaptation reset. Aftermarket transmission additives are not recommended and are not required. AMSOIL 100% Synthetic CVT Fluid may be mixed with the previous CVT fluid if a complete drain-and-fill is not practical, although a full fluid exchange produces the cleanest result.

Cvt fluid
Best fluids. Got enough to flush out transmission 2 times
By Chris from PA on July 12, 2026.
Would recommend this to a friend.
Amsoil CVT Transmission Fluid
Although the vehicle manufacturer states that only authorized fluid is to be used, I have the highest level of confidence in Amsoil products. This time didn't disappoint! The vehicle shifts flawlessly! I use Amsoil products in all of my vehicles and my boat.

Honda HCF-2 support
I have used this in 2 generations of CR-V and 1 Accord CVT. It really quiets down the natural whine these transmissions make.

Frequently asked questions
What is AMSOIL 100% Synthetic CVT Fluid?
AMSOIL 100% Synthetic CVT Fluid is a full-synthetic transmission fluid formulated specifically for belt-type and chain-type continuously variable transmissions in passenger cars and light trucks. It is not an automatic transmission fluid, not a dual-clutch fluid, and not a gear lube. CVT fluids carry a unique metal-to-metal friction profile so the belt or chain grips the pulleys without slipping, and the AMSOIL CVT formulation targets the factory friction specs published for a wide range of Asian, domestic, and European CVT applications.
How often should CVT fluid be changed?
CVT fluid service intervals are set by the vehicle manufacturer and vary by make, model, and duty cycle. Many factory intervals fall in the 30,000 to 60,000 mile range for severe service and run longer under normal service, but the owner manual is the controlling document. AMSOIL 100% Synthetic CVT Fluid is intended to be changed at the OEM-specified interval, with a shorter interval for tow, taxi, mountain, or extreme-temperature use.
Is CVT fluid the same as automatic transmission fluid?
No. CVT fluid is not the same as conventional ATF. Conventional automatic transmissions use planetary gearsets and a different friction profile, while CVTs transmit torque through metal-on-metal contact between a steel belt or chain and pulleys. Substituting ATF in a CVT, or substituting CVT fluid in a planetary automatic, can cause belt slip, shudder, or premature wear. Any vehicle that calls for a specific CVT fluid should be serviced with a CVT-rated fluid that lists the same OEM specification.
Is AMSOIL Synthetic CVT Fluid compatible with Nissan NS-2 and NS-3?
Yes. AMSOIL 100% Synthetic CVT Fluid is recommended for transmissions that require Nissan NS-1, NS-2, and NS-3 specifications, including many Altima, Sentra, Maxima, Versa, Rogue, Murano, Pathfinder, and Infiniti applications. Confirm the exact spec called for in the owner manual, drain and refill to factory level, and follow the manufacturer relearn procedure if the service manual specifies one.
Does using AMSOIL Synthetic CVT Fluid void the factory warranty?
No. Using AMSOIL synthetic lubricants does not void the factory vehicle warranty under the Magnuson-Moss Warranty Act when the lubricant meets the specification called for in the owner manual. AMSOIL 100% Synthetic CVT Fluid is Warranty Secure and is also backed by the AMSOIL Limited Warranty (G1363).
Can AMSOIL Synthetic CVT Fluid help reduce CVT shudder?
CVT shudder is often a fluid-related symptom that appears when frictional properties drift outside spec, especially after high mileage or contamination. Based on JASO LVFA Anti-Shudder Durability testing, AMSOIL Synthetic CVT Fluid lasted six times longer than the test baseline, supporting durable anti-shudder behavior over the service interval. Persistent shudder after a fresh, on-spec fluid change usually points to a mechanical issue and should be diagnosed by a qualified technician.
